The ANVIL INTERNATIONAL INC 8700132403 is a black pipe cap sized for 1-1/2 inch pipe. Pipe caps are threaded fittings used to close off the end of a pipe run, isolating a section of piping or capping unused outlets in a distribution system. This fitting is finished in black, indicating a malleable iron or standard black iron construction typical for gas, compressed air, and non-potable fluid systems. Licensed plumbers, pipefitters, and HVAC technicians install these as part of system pressure testing, permanent termination, or staged rough-in work.
Black pipe caps are used in residential and commercial applications wherever a threaded pipe end requires a secure, pressure-rated closure. Common installations include natural gas branch lines, propane distribution systems, compressed air headers, and steam or hydronic heating piping. This cap threads directly onto the male end of standard black iron or galvanized pipe to create a sealed termination point.
Designed as an OEM-style replacement and standard fitting for 1-1/2 inch threaded black iron pipe systems in residential and commercial plumbing, gas, and HVAC piping applications.
Installation is performed by licensed plumbers or pipefitters following applicable codes such as the IPC or IFGC. Shut off and depressurize the piping system fully before removing or installing any threaded fittings. Apply an appropriate pipe thread sealant or PTFE tape to the male threads before threading on the cap. Pressure-test the completed assembly per local code requirements before returning the system to service.
